Resin flooring is a versatile and durable solution for many surfaces, but applying it to damp or newly laid screeds can cause serious issues. Understanding proper surface preparation is key for a long-lasting finish.
Why Moisture Matters in Resin Flooring
Resin systems rely on a strong bond with the substrate. If there is any remaining moisture within a screed, it can compromise adhesion, leading to delamination or bubbling. Even surfaces that appear dry may retain hidden moisture that only becomes apparent after resin application.
How to Check for Moisture and Prepare the Substrate
Before beginning your resin floor project, allow screeds to cure thoroughly according to manufacturer guidelines—this often takes several weeks. Using a moisture meter provides an accurate assessment of residual dampness. Only proceed when the reading is within the recommended limits for your chosen resin system.
For added security and optimal adhesion, apply a quality primer like the Epoxyprimer Universal Water-Based Two-Component Epoxy Floor Primer, especially if your base surface is concrete, screed, or timber.
When This Matters Most
- During renovations in older properties, where hidden damp may linger.
- For new builds, where screeds may not yet be fully cured.
- In areas exposed to weather or poor ventilation.
